A toy construction block kit is disclosed. The basic unit of the toy construction block unit has three basic sides, with two side walls and a connecting wall. Each of the two side walls have ‘tongues” extending from their interior sides. The back connecting wall has means for reversibly capturing the tongues. The construction block units have two tongues that stick out from opposing walls, and a distal part which contains a double receiving clip. As each construction block unit has the two tongues and a double receiving clip, when two blocks are pushed together, they double lock. The construction block unit can be attached to one or more other construction block units, or could be attached to a blank cube.

A connection device and system is disclosed that is made up of a flexible grid and durable connectors for removable insertion into spaces of the grid.

The invention relates to children's construction kits for assembling building toys from connecting elements. The technical result is an increase in functional capabilities, permitting the assembly of simple and complex spatial constructions with dynamic properties. This technical result is achieved by virtue of a building toy consisting of a set of flat shape-forming and decorative modular elements made of a flexible resilient material and having fastening elements attached to the surfaces thereof, said fastening elements forming detachable joints capable of holding together connected portions of the surfaces, wherein each of the fastening elements takes the form of the centre of axial rotation of at least the held portion of the surface of a connected modular element, and each of the shape-forming modular elements has on its opposite surfaces at least one coaxial pair of fastening elements which are rigidly interconnected and have oppositely oriented mating surfaces.

The invention relates to a building system for creating three-dimensional structures (39), which structures (39) are comprised of a plurality of polyhedralunits (37), each unit (37) being hingedly coupled to at least one adjacent unit (37), wherein the plurality of hinged units (37) are arranged to be interchangeably manipulated between various forms of said three-dimensional structures (39). The system further comprises at least two types of plate-like building elements (3), a single-piece element (1) and a double-piece element (33) that is comprised of two single-piece elements (1) arranged adjacent each other and being hingedly attached to each other at one of the edges (7) of each of the two adjacently arranged single-piece elements (1). An inner portion (5) of each edge (7) of each element (3) is furthermore provided with coupling means (9) arranged for coupling elements (3) together along their edges (7) so as to create polyhedral units (37). Each polyhedralunit (37) of a completed three-dimensional structure (39) is comprised of at least one single-piece element (1) and at least one double-piece element (33). The invention further relates to a three-dimensional structure (39) created by means of the building system.

A toy construction element is disclosed having a body with at least one projection extending therefrom and a plurality of complementary-shaped recesses formed therein. The recesses extend along at least two different axes and are configured for receiving a corresponding projection from like elements so as to allow like construction elements to be interconnected in three dimensions. The projections and/or recesses may be formed with snap-fit interlocking features whereby the element is configured for interlocking engagement with like elements. The snap-fit interlocking features can include complementary locking formations formed on each projection and each recess. The formations are configured to pass over each other as the projection of one element is received in the recess of another element when like elements are assembled, and the recess is at least in part defined by a resilient component that flexes to resist passage of the formations during assembly and disassembly.

A building block assembly (50) comprises a first module (50A) and a second module (50B) which are in detachable engagement, wherein the first module (50A) and the second module (50B) are mechanically connected and relatively rotatable about a rotation axis. The first module (50A) is a building block module comprising a first building block and a second building block which are snap fastened or press fastened to form a building block stack. The second module (50B) is mechanically retained by the first module (50A) in a retention state upon snap fastening of the first building block and the second building block in a connection direction defined by a connection axis which is coaxial with the rotation axis to form the building block stack.

The present invention relates to a cubic element for construction toys, including three, straight, open-ended channels each formed on an adjacent different face of the cube between two opposite faces of the cube and extending in orthogonal opposite directions to each other (X,Y,Z). Each channel includes a bottom wall and two upwardly extending parallel sidewalls, wherein the width of Fa the bottom wall and the distance between the face which is distal to the channel that is extending orthogonally from the same cube face, and the sidewall adjacent the distal face, are substantially equal.

Implementations described and claimed herein provide systems and methods for delivering a customizable feedback stimulus. In one implementation, a custom feedback device comprises a shell housing having a first shell and a second shell. The shell housing opening extends between an outer surface of the first shell and an outer surface of the second shell. A plurality of protrusions extends between the first shell and the second shell, and at least one receiving area is defined by the plurality of protrusions between the first shell and the second shell. The receiving area is adapted to house a customized portion.

An interlocking disc includes a hub with an inner circular area with an inner thickness and a circular step. A plurality of petals circumferentially spaced apart extend radially outward from the outer area of the hub. Each of the plurality of petals are disposed within a common plane and include a catch on each of side of each petal. The catch is engageable to a circular stop of another interlocking disc to inhibit disassembly.

A dog toy comprises a first component having a body that defines a cavity, the body having an opening into the cavity. The dog toy also comprises a second component having a body comprising a first protrusion and a second protrusion. Each of the first protrusion and the second protrusion is selectively insertable into the first component opening in a manner where it remains within the opening to close the opening and is removable from the first component opening when a separation force is applied. The separation force for the first protrusion is different than the separation force for the second protrusion. A treat can be inserted into the first component cavity, the first component cavity can be closed by insertion of the first protrusion or second protrusion into the first component opening, and a dog can gain access to the treat by separating the first component and the second component.
